An unstable atmosphere allowed for isolated thunderstorms to develop. While overall conditions were not conducive to an increased risk of severe weather, one thunderstorm produced local winds over 60 mph at a local airport as it collapsed.

The episode as NWS IWX wrote it up.
An unstable atmosphere allowed for isolated thunderstorms to develop. While overall conditions were not conducive to an increased risk of severe weather, one thunderstorm produced local winds over 60 mph at a local airport as it collapsed.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Northern Indiana wrote its last area forecast discussion before the first event at May 27, 6:57 PM EST, 7 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NORTHERN INDIANA 757 PM EDT TUE MAY 27 2014 .SYNOPSIS... ISSUED AT 755 PM EDT TUE MAY 27 2014 A COLD FRONT IN MICHIGAN WILL DROP SOUTHWARD INTO INDIANA TONIGHT BRINGING A CHANCE FOR SHOWERS AND THUNDERSTORMS WITH IT. LOW TEMPERATURES TONIGHT WILL BE IN THE 60S WITH COOLER CONDITIONS NEAR LAKE MICHIGAN. HIGHS TOMORROW WILL BE NEAR 80...EXCEPT AGAIN COOLER NEAR THE LAKE...ALONG WITH A CHANCE OF SHOWERS AND THUNDERSTORMS. && .SHORT TERM...(THIS EVENING THROUGH WEDNESDAY) ISSUED AT 352 PM EDT TUE MAY 27 2014 HIGHLY DIFFUSE COLD FRONT CONTINUES TO SLOWLY PUSH SOUTH ACROSS THE GREAT LAKES TODAY...IN A BACKGROUND SYNOPTIC ENVIRONMENT UNFAVORABLE FOR INCREASING BAROCLINICITY/FRONTOGENESIS. COLD/STABLE LAKE AGGREGATE IS STILL AIDING THE SOUTHWARD PUSH OF THIS WEAKLY CONVERGENT FRONTAL BOUNDARY BUT LATEST SURFACE ANALYSIS SHOWS BEST FOCUS FOR CONVECTION REMAINS JUST NORTH OF OUR CWA. PLENTY OF MOISTURE IN PLACE THOUGH WITH REGIONAL 12Z RAOBS INDICATING AROUND 1.5 INCHES OF PW. THESE VALUES ARE LIKELY HIGHER NOW AS MOISTURE POOLS ALONG AND AHEAD OF THE FRONT. SURFACE DEWPOINTS HAVE CREPT TO NEAR 70F ACROSS EXTREME NORTHERN INDIANA AND SOUTHERN LOWER MICHIGAN. DESPITE AMPLE LOW LEVEL MOISTURE...INSTABILITY HAS BEEN AND WILL CONTINUE TO BE ON THE MARGINAL SIDE DUE TO WARM TEMPS ALOFT/PALTRY MIDLEVEL LAPSE RATES. WITH A LACK OF CLEAR SYNOPTIC TRIGGER...OVERALL MODEST CAPE VALUES...AND LITTLE TO NO BULK SHEAR...PULSE/MULTICELL CLUSTERS WILL CONTINUE TO BE THE DOMINANT STORM TYPE WITH AN OVERALL LOW RISK OF SEVERE WEATHER. CIN VALUES ARE ALSO VERY LOW AND CONVECTION CONTINUES TO FIRE ALONG SEVERAL OLD/PREEXISTING OUTFLOW BOUNDARIES. HEAVY RAIN IS STILL THE BIGGEST THREAT GIVEN AMPLE TROPOSPHERIC MOISTURE...WEAK FLOW ALOFT THAT IS ALSO PARALLEL TO THE FRONT...AND EFFICIENT WARM RAIN COLLISION/COALESCENCE PROCESSES. VERY LOW MBE VELOCITIES ALSO SUGGEST THE POTENTIAL FOR SLOW MOVING AND POTENTIALLY BACKBUILDING STORMS. COLD FRONT WILL CONTINUE TO SAG SOUTH THIS EVENING AND OVERNIGHT. ONCE AGAIN LOSS OF DAYTIME HEATING WILL EVENTUALLY LIMIT PRECIP POTENTIAL BUT WILL PROBABLY SEE SCT CONVECTION CONTINUING THROUGH MUCH OF THE OVERNIGHT PERIOD SIMILAR TO LAST NIGHT. AFTERNOON WATER VAPOR DOES SHOW A WEAK VORT MAX SPINNING OVER SOUTHEAST MINNESOTA. THIS WAVE WILL CONTINUE TO MOVE SOUTHEAST AND WIND DOWN/FLATTEN OUT BUT VERY SUBTLE HEIGHT FALLS MAY BE ENOUGH TO KEEP A FEW SHOWERS AND THUNDERSTORMS GOING THROUGH THE MORNING HOURS. BETTER CHANCES FOR MORE WIDESPREAD COVERAGE EXPECTED LATE TOMORROW MORNING AND INTO THE AFTERNOON ACROSS THE SOUTHERN HALF OF OUR CWA. FRONT WILL BE JUST CROSSING OUR AREA DURING THAT TIME AND ENHANCED LOW LEVEL CONVERGENCE COUPLED WITH ONE MORE ROUND OF DIABATIC HEATING AND MOISTURE POOLING ALONG THE FRONT SHOULD ALLOW FOR SCT/NUM THUNDERSTORMS IN OUR SOUTHERN COUNTIES. ONCE AGAIN HEAVY RAIN WILL BE THE MAIN THREAT FOR THE SAME REASONS NOTED ABOVE. AN ISOLATED WET MICROBURST CAN NEVER BE COMPLETELY RULED OUT IN THIS ENVIRONMENT BUT POTENTIAL IS LOW BOTH TONIGHT AND TOMORROW. && .LONG TERM...(WEDNESDAY NIGHT THROUGH TUESDAY) ISSUED AT 352 PM EDT TUE MAY 27 2014 BROAD LONGWAVE RIDGE CENTERED OVER THE MISSISSIPPI RIVER VALLEY WILL CONTINUE TO INFLUENCE THE WEATHER FOR THE LONG TERM FORECAST PERIOD. INCREASING BOUNDARY LAYER MOISTURE COMBINED WITH MAX TEMPS AT/NEAR CONVECTIVE TRIGGER EXPECT TO SEE CONTINUED -SHRA/-TSRA THROUGH MUCH OF THE PERIOD. SHORTWAVE AND ASSOCIATED FRONT/TROF TO SWEEP SOUTH ACROSS THE GREAT LAKES REGION LATE THURS/FRIDAY AND THIS SHOULD PROVIDE THE BEST CHANCE OF ORGANIZED CONVECTION...ESPECIALLY ALONG THE SOUTHERN PORTION OF THE FORECAST AREA. BOUNDARY LAYER FLOW AND ABUNDANT MOISTURE CONVERGENCE SUGGESTS THAT THESE COULD BE VERY EFFICIENT RAIN PRODUCING STORMS. WILL BEAR WATCHING AS THE WEEK UNFOLDS. FFG IS QUITE HIGH AT THIS TIME AND THE WARMTH OF THE PAST COUPLE WEEKS MOST SOILS SHOULD BE ABLE TO HANDLE MOST OF THE RAINFALL. TEMPERATURES TO REMAIN ABOVE NORMAL THROUGH THE PERIOD AND HAVE MADE LITTLE CHANGE TO EXISTING FORECASTS. && .AVIATION...(FOR THE 00Z TAFS THROUGH 00Z WEDNESDAY EVENING) ISSUED AT 755 PM EDT TUE MAY 27 2014 CONVECTION FIRING NEAR KSBN AIRFIELD ALONG OUTFLOW BOUNDARY EMANATING FROM SOUTHERN LAKE MICHIGAN STORMS PLUS LAKE BREEZE COMPONENT. ANTICIPATE UPSTREAM STORMS TO CONTINUE FOCUS ALONG THIS BOUNDARY FOR ABOUT NEXT 3 HOURS UNTIL STABILITY INCREASES. OTHERWISE...HIGH XOVER TEMPS ESPECIALLY AT KSBN SUGGEST POTENTIAL SIGNIFICANT VSBY REDUCTIONS IN BR TOWARD DAYBREAK. ADDITIONAL STORMS POSSIBLE AS SHALLOW FRONT PUSHES SOUTHWARD THROUGH NORTHERN INDIANA WED AFTERNOON...MOST LIKELY AT/NEAR KFWA WHERE DRIER/STABLE BOUNDARY DEPTH NOT AS DEEP. && .IWX WATCHES/WARNINGS/ADVISORIES...
